1. A bicycle tire is inflated to a pressure of 3.74 atm at 15°C. If the tire is heated to 35°C, what is the pressure in the tire? Assume the tire volume doesn’t change.
2. A cylinder is filled with toxic gas to a pressure of 800.0 torr at 24°C. According to the manufacturer’s specification, the cylinder may rupture if the pressure exceeds 35 psi (pounds per square inch: 1 atm = 14.7 psi). What is the maximum temperature to which the cylinder could be heated without exceeding this pressure rating?
3. A sample of a smokestack emission was collected into a 1.25-L tank at 752 mm Hg and analyzed. The analysis showed 92% CO2, 3.6% NO, 1.2% SO2, and 4.1% H2O by mass. What is the partial pressure exerted by each gas?
4. During a collision, automobile air bags are inflated by the N2 gas formed by the explosive decomposition of sodium azide, NaN3.
What mass of sodium azide would be needed to inflate a 30.0-L bag to a pressure of 1.40 atm at 25°C.
5. You want to store 165 g of CO2 gas in a 12.5-L tank at room temperature (25°C). Calculate the pressure the gas would have using (a) the ideal gas law and (b) the van der Waals equation. (For CO2, a = 3.59 atm L2/mol2 and b = 0.0427 L/mol.)
